 The temperature range of the meter extends up to 1300°C (2372°F), however thermocouple sensor ranges vary greatly; be sure to select a

thermocouple rated for the expected temperature measurement ranges.

 Accuracy specified for meter only. Thermocouple probes add additional measurement error.

 The above specifications are tested under an environmental RF Field Strength lower than 3 V/M and a frequency lower than 30 MHz
